Abstract
Statistics
Introduction and objectives: The main objective of this study was to compare the single leg static and dynamic equilibrium data between gender of subjects and dominant and non-dominant limbs.Participants: A total of 20 physically active subjects, 10 men and 10 women (ages: 22.56 ± 5.7 years).Methods: We measured the mean amplitude of lateral and anteroposterior deviation of the pressure centre (PC) by means of an optometric platform using three single leg tests with progressive difficulty: open eyes (OE), closed eyes (CE) and one leg hop (H).Results: There were no significant differences between men and women in the OE test. The CE test showed significant differences in the anteroposterior and lateral plane in the non-dominant leg (p < 0.029 and p < 0.035, respectively). As regards the H test, the results showed significant differences in dominant and no-dominant leg only in the frontal plane (p < 0.011 and p < 0.002, respectively). There were no significant differences between legs; but when the groups were analysed separately by gender differences were found in both planes of the H test in women and anteroposterior axe of OE test in men.Conclusion: Women tend to show lower PC sway in the more dynamic tests (CE and H) compared to men. Although there were no differences between legs in the total group, it was found that women showed a greater PC sway in the non-dominant leg when landing in the one leg hop test compared with men.
